I wonder where Mr Sin gets that confidence after getting his arse handed to him by Jiyong despite being in his own turf and the weight class difference.
As for lawyer Jo, one has to give it to him: mustering the willpower to stop squirming, pretend to die and even pee himself to make it realistic, and then wait for Mr Sin to leave the room before releasing himself… the man has the brain and the brawn. I was a little surprised at how quickly he died, that kind of hanging takes a couple minutes, but I genuinely believed that was the last we saw of him.
Oh, well, not like I'm not used to protagonists and antagonists in this series being experts in 5D chess.
